Doom

The Intel Core i5-14400F and NVIDIA GeForce RTX 3080 combination delivers a formidable 1080p and 1440p experience in Doom, with 4K also remaining highly playable. The data shows a system that comfortably exceeds the 60 FPS playable threshold at every tested setting and resolution, making this a pairing with substantial headroom for high-refresh-rate displays.

Similar Performance Alternatives

The Intel Core i5-14400F sits in a tightly contested performance band. Its average benchmark score of 32279 places it within 0.5% of several close competitors. The AMD Ryzen 7 PRO 8840U averages 32233, a delta of just 0.1% slower, making it a near-identical match in synthetic workloads. Similarly, the Intel Core i9-11900 scores 32226, also 0.2% behind, while the AMD Ryzen 7 6800HS trails by a mere 0.2% with a score of 32354. The Intel Core i7-12800H completes this cluster, scoring 32121, which is 0.5% lower. In practical terms, swapping the i5-14400F for any of these rivals would yield imperceptible differences in Doom’s frame rates, as the CPU is unlikely to be the primary bottleneck at the tested settings.

On the graphics side, the RTX 3080’s position is more distinct. Its average benchmark score of 23172 places it in the 68th percentile of all GPUs. Its nearest rivals, however, are not direct performance equivalents. The NVIDIA P106-100, AMD Radeon Pro Vega 16, AMD Radeon RX 6600M, and AMD Radeon R9 M290X all post average scores within 0.4% of the RTX 3080 (23249, 23250, 23273, and 23276, respectively). While the synthetic scores are close, the RTX 3080’s architectural advantages, such as its 10 GB of GDDR6X memory and 320-bit bus, suggest its real-world gaming performance, particularly at higher resolutions, would outpace these rivals despite the statistical tie in aggregate benchmarks. For Doom, the RTX 3080 is the dominant component, and these rivals would likely produce lower frame rates in GPU-bound scenarios.

How This Combo Ranks

Within the database of tested CPU and GPU combinations for Doom, this pairing ranks 1081 out of 3712 combos. This places it in the top 29% of all tested systems, indicating a strong overall performance level. The rank reflects the balance between the i5-14400F’s capable multi-core performance and the RTX 3080’s high-end rasterization power. The data suggests that while this is not the absolute top-tier configuration possible, it outperforms the vast majority of systems tested in this specific title. The high frame rates observed across all resolutions, particularly the 180.4 FPS average at 1080p Ultra, justify a ranking that places it firmly in the upper quartile of tested hardware.

Measured FPS Breakdown

The measured frame rates for this combination show a clear scaling pattern across resolutions and presets. At 1920x1080, the system is overwhelmingly GPU-bound with massive headroom. The Low preset averages 299.3 FPS, which drops to 261 FPS at Medium, 223.6 FPS at High, and 180.4 FPS at Ultra. These figures indicate that even the most demanding preset leaves performance on the table for 240Hz monitors.

Moving to 2560x1440, the frame rates remain exceptionally high. The Low preset delivers 195.5 FPS, Medium averages 169.3 FPS, High achieves 145.2 FPS, and Ultra still maintains a robust 115.6 FPS. The scaling from 1080p to 1440p is roughly a 35-38% reduction in frame rate across all presets, which is consistent with the increased pixel count straining the GPU.

At 3840x2160, the RTX 3080 begins to feel the pressure, but the results are still playable. The Low preset averages 104.3 FPS, Medium drops to 92 FPS, High settles at 76.4 FPS, and Ultra falls to 62.4 FPS. The 4K Ultra result is just above the 60 FPS playable threshold, showing that the GPU’s 10 GB memory and 760.3 GB/s bandwidth are sufficient for this title at maximum settings, though with less headroom than at lower resolutions.

FAQ

*Q: Can this system run Doom at 4K Ultra settings?*

A: Yes. The measured average frame rate at 3840x2160 with Ultra settings is 62.4 FPS, which is above the 60 FPS playable threshold.

Q: What is the highest average frame rate this combo achieves at 1080p?

A: The highest average frame rate is 299.3 FPS, achieved at 1920x1080 with the Low preset.

Q: How much performance is lost when moving from 1080p to 1440p?

A: At the Ultra preset, the average frame rate drops from 180.4 FPS at 1080p to 115.6 FPS at 1440p, a reduction of roughly 36%.

Q: Is the CPU or GPU the limiting factor at 4K?

A: The data indicates the GPU is the primary constraint at 4K. The frame rate scaling from 1440p to 4K at Ultra (115.6 to 62.4 FPS) shows a significant drop, which is characteristic of GPU-bound rendering.

Q: Which preset at 1440p provides the best balance of visual quality and performance?

A: The Ultra preset at 2560x1440 still delivers a high average of 115.6 FPS, making it the recommended choice for maximum visual fidelity without sacrificing smoothness.

Q: Does the system ever drop below 60 FPS in the tested scenarios?

A: No. Every resolution and preset combination tested yields an average frame rate above 60 FPS, with the lowest being 62.4 FPS at 4K Ultra.

CPU and GPU Roles

The benchmark data reveals a clear division of labor between the Intel Core i5-14400F and the NVIDIA GeForce RTX 3080 in Doom. At 1920x1080, the frame rates are extraordinarily high, with the Low preset hitting 299.3 FPS. This suggests the CPU is capable of feeding the GPU at very high rates, but the GPU is still the limiting factor as settings increase. The drop from 299.3 FPS at Low to 180.4 FPS at Ultra is a 40% reduction, indicating that the GPU’s workload scales significantly with preset quality.

At 2560x1440, the GPU’s role becomes more pronounced. The frame rate at Ultra (115.6 FPS) is roughly 60% of the 1080p Ultra figure, directly reflecting the 1.78x increase in pixel count. The CPU, with its 10 cores and 16 threads, maintains sufficient throughput to avoid becoming a bottleneck even at these elevated frame rates.

The 4K results decisively show the GPU as the dominant constraint. At 3840x2160, the Ultra preset averages 62.4 FPS, while the Low preset averages 104.3 FPS. The performance gap between Low and Ultra at 4K is 40%, similar to the 1080p scaling, but the absolute numbers are much lower. This confirms that the RTX 3080’s shading units, texture units, and memory bandwidth are fully utilized at 4K, while the i5-14400F has ample headroom. The CPU’s role is to provide a stable foundation, but it is not the performance limiter in any tested configuration.

Best Settings per Resolution

For each resolution, the most demanding preset that maintains an average frame rate at or above 60 FPS is the Ultra preset. The data confirms that this combination can handle maximum settings at all three tested resolutions.

• 3840x2160: Ultra is playable with an average of 62.4 FPS. This is the highest quality setting and stays just above the 60 FPS threshold.
• 2560x1440: Ultra is the best choice, delivering a comfortable 115.6 FPS average. This provides high visual fidelity with significant performance headroom.
• 1920x1080: Ultra is recommended, achieving an excellent 180.4 FPS average. This is ideal for high-refresh-rate monitors, as the system can easily push beyond 144 FPS at maximum quality.

In all cases, the Ultra preset is the optimal choice. The system’s performance at lower presets (Low, Medium, High) is only relevant if a user prioritizes extreme frame rates over visual quality, but the data shows that Ultra settings do not compromise the 60 FPS playability at any resolution.
